A B-Lymphocytes I Passive immunity B Interferons II Cell mediated immunity

Question

Match List I with List II :

	List - I		List – II
A	B-Lymphocytes	I	Passive immunity
B	Interferons	II	Cell mediated immunity
C	T-Lymphocytes	III	Produce an army of proteins in response to pathogens
D	Colostrum	IV	Innate immunity

Choose the correct answer from the options given below : 

(1) A-I, B-IV, C-II, D-III 

(2) A-IV, B-II, C-III, D-I 

(3) A-III, B-IV, C-II, D-I 

(4) A-II, B-IV, C-I, D-III 

Answer 1

Correct option is (3) A-III, B-IV, C-II, D-I

The correct answer is option (3) as

• The B-lymphocytes produce an army of proteins in response to pathogens into our blood to fight with them. These proteins are called antibodies.
• Interferons belong to the cytokine barrier of innate immunity, which protect non-infected cells from further viral infection.
• T-lymphocytes mediate cell mediated immunity.
• Colostrum provides natural passive immunity to the infant.
